AN2111: Heterodyne with Quadrature Outputs, PSoC Style

The unique configuration of the PSoC switched-capacitor blocks allows construction of analog modulators. These modulators allow the mixing of an input signal with a reference signal resulting in a frequency shift of the input signal. This Application Note will show that with a little understanding, frequency shifting with a switch-capacitor modulator becomes a straightforward operation.
